Abstract

A method and apparatus for displaying an optimal path of moving objects, capable of providing forward path information of while the vehicle is waiting for its traffic signal at an intersection or is in a standstill state, in a navigation device are provided. An optimal path is set and stored according to a destination of a moving object. A current position of the moving object traveling along the optimal path is detected. When the moving object stops on the optimal path, it is determined if a traveling-stopped time of the moving object is greater than or equal to a predetermined time. When the traveling-stopped time of the moving object is greater than or equal to the predetermined time, a forward path for the detected current position of the moving object is displayed.

Claims

1. A method for displaying an optimal path of a moving object in a navigation device, the method comprising the steps of:

setting and storing an optimal path according to a destination of a moving object;

detecting a current position of the moving object traveling along the optimal path;

determining whether a traveling-stopped time of the moving object is greater than or equal to a predetermined time, when the moving object stops on the optimal path; and

displaying a forward path for the detected current position of the moving object, when the traveling-stopped time of the moving object is greater than or equal to the predetermined time.

2. The method of claim 1, wherein the forward path is an optimal path in a forward area, and the forward area is an area within a predetermined scope from the current position of the moving object on the optimal path.

3. The method of claim 2, wherein displaying a forward path comprises displaying the moving object virtually traveling in the forward area.

4. The method of claim 1, wherein displaying a forward path comprises displaying the forward path on a sub-screen divided from a display screen.

5. The method of claim 1, further comprising:

upon receiving a user input for display of the forward path, displaying the forward path for the current position of the moving object.

6. The method of claim 1, further comprising:

upon receiving a user input for stopping the display of the forward path, stopping the display of the forward path of the moving object.

7. A method for displaying an optimal path of a moving object in a navigation device, the method comprising the steps of:

setting and displaying an optimal path according to a destination of a moving object;

detecting a current position of the moving object traveling on the optimal path;

determining whether a user input for display of a forward path is received, when the moving object stops on the optimal path; and

upon receiving the user input for display of the forward path, displaying the forward path for the current position of the moving object.

8. The method of claim 7, further comprising:

upon receiving no user input for display of the forward path, measuring a traveling-stopped time of the moving object; and

displaying the forward path for the current position of the moving object, when the traveling-stopped time of the moving object is greater than or equal to a predetermined time.

9. The method of claim 7, wherein the forward path is an optimal path in a forward area, and the forward area is an area within a predetermined scope from the current position of the moving object on the optimal path.

10. The method of claim 9, wherein displaying the forward path comprises displaying the moving object virtually traveling in the forward area.

11. The method of claim 7, wherein displaying the forward path comprises displaying the forward path on a sub-screen divided from a display screen.

12. The method of claim 7, further comprising:

upon receiving a user input for display of the forward path, displaying the forward path for the current position of the moving object.

13. The method of claim 8, further comprising:

upon receiving a user input for stopping the display of the forward path, stopping the display of the forward path of the moving object.

14. A method for displaying an optimal path of a moving object in a navigation device, the method comprising the steps of:

setting and displaying an optimal path according to a destination of a moving object;

detecting a current position of the moving object traveling on the optimal path;

determining whether a first intersection is situated within a predetermined first scope from the detected current position of the moving object, when the moving object stops on the optimal path;

determining if a second intersection is situated within a predetermined second scope, when the first intersection is situated within the predetermined first scope; and

displaying a forward path for the current position of the moving object, including the first intersection and the second intersection, when the second intersection is situated within the predetermined second scope.

15. The method of claim 14, further comprising:

displaying the forward path for the current position of the moving object, including the first intersection, when no second intersection is situated within the predetermined second scope.

16. The method of claim 14, wherein the forward path is an optimal path in a forward area, and the forward area is an area within a predetermined scope from the current position of the moving object on the optimal path.

17. The method of claim 16, wherein displaying the forward path comprises displaying the moving object virtually traveling in the forward area.

18. The method of claim 17, wherein displaying the forward path comprises displaying the forward path on a sub-screen divided from a display screen.

19. The method of claim 14, further comprising:

upon receiving a user input for display of the forward path, displaying the forward path for the current position of the moving object.

20. The method of claim 14, further comprising:

upon receiving a user input for stopping the display of the forward path, stopping the display of the forward path of the moving object.

21. An apparatus for displaying an optimal path of a moving object in a navigation device, the apparatus comprising:

a map data database (DB) for storing map data used for providing an optimal path based on a destination of a moving object;

a position detector for detecting a current position of the moving object traveling along the optimal path;

a display for displaying the optimal path and the current position of the moving object; and

a controller for setting the optimal path using the map data, determining if a traveling-stopped time is greater than or equal to a predetermined time when the moving object stops on the optimal path, and controlling the display to display a forward path for the current position of the moving object when the traveling-stopped time is greater than or equal to the predetermined time.
